UNITED STATES ALBERT BRAND, OF MUNICH, GERMANY.

MACHINE FOR PRINTING AMPULLE.

Application filed December 9, 1925, Serial No. 74,412, and in Germany February 4, 1924.

This invention relates to :1 machine for printing ampullae in which the printing block inked by a Slidable inking mechanism is mounted in a printing head designed. to

5 execute a reciprocating down and up move ment. According to the invention the ampulla, inserted underneath the inking carriage is rolled by this inking carriage over a, rubber plate which is preferably elastically mounted and by which the ampulla is printed as the text to be printed on the ampulla has been previously printed as negative upon the rubber plate by the printing block of the printing head.

An embodiment of the invention is shown, by Way of example, in the accompanying drawing in which- 1 Fig. 1 shows in plan view a portion of the improved ampullae-printing machine.

Fig. 2 is a side elevation and Fig. 3 a front elevation.

In the frame of the machine a worm shaft a is journalled which drives a spur wheel 6. From the spur wheel I) the inking mechanism is driven by an eccentric rod 0. The

inking mechanism is composed of the inking rollers d and the rubber plate e to which a rotative movement is communicated at every backward movement by a rod 7 fixed on the eccentric rod 0. A cam g projecting from the spur wheel 6 serves to intermittently operate a lever 72. carrying the printing head 2' in which the printing block is mounted.

A spring 0 serves to return the lever it into its initial position after each operation. The

types in the printing block are positive.

Under the printing head 2' a rubber plate is is arranged onto which the printing. block prints a negative copy of the text at each descending movement of the printing head i. The ampullae are placed by hand under the carriage Z of the inking mechanism behind the rubber plate lVhen the carriage l movesin forward direction for inking the printing block on the printing head i (posi- 5 tion shown in dotted lines) the Carriage l rolls the ampulla over the rubber plate Z: from which the negative print received from the printing block is transferred as positive print onto the ampuila.

The support m for the rubber plate Z: yieldably mounted by means of spiral springs 11. so that slightdifi'erence in the (Miss sections of the ampullae is accounted for.

I claim:

A machine for printing a-mpnllac, compris-. ing in combination with the machine frame a printing head containing positive type. 'a main driving shaft, means for comnnmicating a reciprocating movement in vertical di-' rection from said main driving shaft to said printing head, a rubber plate underneath said printing head an elastic support for said rubber plate, an inking mechanism mounted on a carriage, means for connnunicating to said carriage of the inking mechanisms a forward and backward movement so that an ampulla placed by hand behind said rubber plate is rolled over said rubber plate by the moving carriage of the inking .mcchanism and the negative copy of the text. printed onto said rubber plate by said dcscending printing head is transferred onto the ampulla.

In testimony whereof I afiix my signature.

ALBERT BRAND.
